Simplify autogen.sh

Replace the whole autogen.sh magic by four simple lines that execute the
commands that are actually needed.

This enables verbose error output and allows advanced users to figure
out what went wrong in case of errors. We expect users building calcurse
from Git to be smart enough to fix "command not found" errors by
themselves.
